UNITED EDMUND E. HAR'rsHoRN, 0E lNEWARK,l ivEw JERSEY, AssIenoR fro STEWART EARTs- HoRN CoMPANY, or EAs'r NEWARK, NEW JERSEY, A CORPORATION or NEW JERSEY.

Application filed .Tune 4, 1914., Serial No. 842,822.' I A To all 'whom t may concern Be it known that I, EDMUNDy F. HAR'rs- HORN, a citizen of the United States, residing in the city of Newark, county of Essex, State of New Jersey, have inventeda certain new and useful Improvement in Shade- Rollers, of which the vfollowing is a specification.

The invention relates .to rollers ofthe type whereinno pawl is used and which are particularly applicable for car windows, in which the curtain or shade `is held in eX- pandedposition by a fastening deviceadjacent to the lower edge thereof.- v The principal object of the invention is to provide a device for locking the spring in wound-,up condition when-the roller is removed'from its brackets, so that it may be replaced without the spring 1in-winding. This and further objects will more fully appear from the followingy specification and accompanying drawings, considered together orseparately, in lwhich: Y 1

Figure 1 is an elevation of part of a-window frame showing a shade and roller embodying my invention; Fig. 2 is a longitudinal section of the roller; Fig. 3 is a transverse section on vthe line 3 of Fig. 2, looking in the direction of the arrow; Fig. 4 is an enlarged sectional view of the spear end of the roller; Fig. 5 is` a transverse section thereof on the line 5-5 of Fig. 4, looking in the direction of the arrow, and showing the parts in unlocked position; Fig. 6 is a similar view, showing the parts in locked position; and Fig. 7 is an end view of the spear and locking arms.

In all of the views, like parts are designated by the same reference characters.

In the drawings, the window frame 1 is provided, as shown, with the usual hood 2, which conceals the roller from view. The roller 3 carries the shade 4. One end of the roller is supported in the pin bracket 5. The other end of the roller is supported in the spear' bracket 6. This latter bracket has the usual notch by means of which the spear may be lifted out. The end of the roller is inclosed by means of a cap 7. This cap has a central opening forming a bearing for the spear 8. The spear is connected to a rod 9, Surrounding this rod is the usual spring 10 with one end connected to the cap so that the roller will be rotated by the unwinding of the spring.

Specification ofl Letters Patent.

SHADE-ROLLER.

Patented 0015.24, 1916.

A groove extends longitudinally on the roller( In this groove 11 is a Wire 12.` yThe shade is doubled koverthe wire as shown.

'It is thereby held in place within they groove.

There isa notch 13 in the cap in line with the groove. On Vthe spear is an arm 14. lVhen .the shade is in the usual operative position this arm 14 will turn clear of the end of the wire 12. By sliding the wire4 and shade longitudinally it Vis brought within the path of rotation of the arm 14, and the arm engaging with the wire will be prevented froml rotating. This wire, therefore, serves kas a shade support, and by a longitudinal movement, the wire, in connection with the arm, serves as arneans, actuated by the vmovement of the wire, to lock the spring in wound-up condition. I have shown the arm 14ias projecting from opposite sides of the spear, but such an arrangement isk solely for purposes of illustrating patent statutes, I have described the principle of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention can be carried out in other ways.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A shade rollerhaving ay spear and a spring, a longitudinal groove in the roller, means for supporting a shade inthe groove, vsaid means being movable longitudinally and means actuated by such movement to lock the spring against unwinding.

2. A shade roller having a spear and a spring, a longitudinal groove in the roller, means for supporting a shade in the groove, said means being movable longitudinally of the roller, and an arm carried by the spear and interposed in the path of the shade supporting means, whereby when the supporting means are moved longitudinally the spring will be locked against unwinding.

3. A shade roller having a spear, a spring, and a longitudinal groove, a shade supporting wire within the groove capable of longitudinal movement, and means actuated by such movement to lock the spring in wound-up condition.

4. A shade roller having a spear, a spring,

lfingitidinalfmoveinent, "and an arm Carried bythe epe-af anda-)ating in the path of the wire, when. longitudinally moved,

whereby the springV- will lbeV locked in Y wennd-uqo-v condition` l .A

` )5. A shade roller having 4a speana spring4 and a longitudinal groove,`*a^-s'hade`supporting wireA Within thegroove'and vcapable of lengitudiiral i movement, and anfarm carried blygthe spearand engaged by the wire when t e latterismoved longitudinally. I'
